	Funding: Operated by Fermi Research Alliance, LLC under Contract No. DE-AC02-07CH11359 with the United States Department of Energy. During slip stacking in the Recycler, up to six batches of 84 bunches each are slipped by each other to and then captured to double the intensity of the the extracted beam. For nominal chromaticity settings, a bunch by bunch transverse damper system is needed to maintain beam stability but this system is blind to the bunches as they are slipping. The initial solution was to drastically raise the chromaticity to keep the beam stable. A new frequency based damper using diode detectors was developed to provide damping during slip stacking and allow the chromaticity to be reduced to nominal settings.

WE3AB3	Commissioning and First Results of the Electron Beam Profiler in the Main Injector at Fermilab	330

	The planned neutrino program at Fermilab requires large proton beam intensities in excess of 2 MW. Measuring the transverse profiles of these high intensity beams is challenging and often depends on non-invasive techniques. One such technique involves measuring the deflection of a probe beam of electrons with a trajectory perpendicular to the proton beam. A device such as this is already in use at the Spallation Neutron Source at ORNL and a similar device has been installed in the Main Injector at Fermilab. Commissioning of the device is in progress with the goal of having it operational by the end of the year. The status of the commissioning and initial results will be presented.

The planned neutrino program at Fermilab requires large proton beam intensities in excess of 2 MW. Measuring the transverse profiles of these high intensity beams is challenging and often depends on non-invasive techniques. One such technique involves measuring the deflection of a probe beam of electrons with a trajectory perpendicular to the proton beam. A device such as this is already in use at the Spallation Neutron Source at ORNL and a similar device has been installed in the Main Injector at Fermilab.
